3.2 Locating the Equipment
3.2.1 Environment
The equipment should be located indoors in an environment that protects it from direct sunlight, moisture, and dust. Changes in temperature,
humidity, and airborne pollution will affect the environment in which the equipment is operating and may impair the safety and operation. It is the
customers' responsibility to ensure that the environmental conditions specified for the equipment are maintained.
3.2.2 Space Requirements
The equipment should be mounted on a flat surface capable as a minimum of supporting its own weight plus the weight of all ancillary parts. The
minimum footprint requirements are specified below, however there must be adequate space around the equipment to allow airflow and access
for maintenance purposes and lifting equipment. A minimum spacing of approximately 500mm (20 ins) is recommended around all sides of the
generator and 1000mm (39.4 ins) above it to allow service operations.
Do Not
position the equipment so that it is difficult to operate or disconnect from the electrical supply.
3.2.3 Air Inlet Quality
ISO 8573-1:2010 is an international standard that specifies the purity classes of compressed air with respect to solid particulates, water and oil.
The air inlet quality specified for this generator is ISO 8573-1:2010 class 2.2.2 and equates to the following:
Class 2 (Solid Particulate)
In each cubic metre of compressed air, not more than:
•
400,000 particles in the 0.1–0.5 micron size range are allowed.
•
6,000 particles in the 0.5–1 micron size range are allowed.
•
100 particles in the 1–5 micron size range are allowed.
Class 2 (Water)
A pressure dewpoint of -40
o
C/-40
o
F or better is required and no liquid is allowed.
Class 2 (Oil)
In each cubic metre of compressed air, not more than 0.1 mg of oil is allowed.
Note. This is the combined level for aerosol, liquid and vapour.
ISO 8573-1:2010 Class 2.2.2 can be achieved with the following combination of Parker purification products:
•
General Purpose filter Grade AO
•
High efficiency filter grade AA
•
ACS / OVR Adsorption Filter
•
General Purpose Dust removal Filter Grade AR
•
PNEUDRI -40
o
C/-40
o
F PDP dryer
Due to the nature of operation there is a possibility of oxygen enrichment surrounding the generator. Ensure that the area is adequately
ventilated. Where the risk of oxygen enrichment is high, such as a confined space or poorly ventilated room, the use of oxygen monitoring
equipment is advisable.
